Musculoskeletal System Working Together
The musculoskeletal system is the working combination of bones, joints, and muscles that supports the body and produces movement.
Practice This ConceptMain explanation
Teacher explanation
Bones provide a firm framework, joints allow movement between bones, and muscles contract to pull bones. Muscles work in pairs because they can pull but cannot push.
Example
When the biceps contracts and triceps relaxes, the forearm bends at the elbow joint.
Simple analogy
Muscles pull, joints pivot, bones move.
Common confusion
Students often write that muscles push bones, but muscles mainly pull bones by contracting.
Exam tip
For movement questions, mention bone as lever, joint as point of movement, and muscle contraction as the force.
